i tried for zero sleep. Minimized it. Circles under eyes but I
  didn't care. But I get some now. Lots of nicotene and caffeine
  and staying up all night to avoid as much of the day as
  possible. Works well so far. Cut my sleep into two 3 hr periods
  so I _appear_ to be awake 24/7. Nobody knows how I do it tongue
